Abstract
In this article, TEMPO-oxidized cellulose nanofiber (TEMPO-CNF) prepared from bagasse was described and utilized as a sustainable material for the preparation of new nanocomposites. TiO2 nanoparticles were synthesized by in situ precipitation in the presence of TEMPO-CNF. The prepared nanocomposite, TEMPO-CNF/TiO2, was characterized by using FT-IR, XRD, TGA, SEM, and EDX analysis. The results proved that homogenous spherical TiO2 nanoparticles were formed with the particles of TEMPO-CNF. TEMPO-CNF/TiO2 nanocomposite was examined as an adsorbent for Brilliant Blue (BB) adsorption. The highest BB removal efficiency was observed at pH 7, the adsorption process is well described by pseudo-second-order and Langmuir adsorption model, and the maximum adsorption capacity is 162 mg/g. Our results proved that the TEMPO-CNF/TiO2 nanocomposite could be used for the removal of BB from aqueous solutions.
